MIAMI (CBSMiami/AP) — Reality star Kelly Osbourne was probably seeing stars after being treated for a head injury in Miami.

Osbourne was admitted to Mercy Hospital and released on Monday, according to Osbourne who tweeted about the incident.

The 27-year-old E! Fashion Police co-host wrote on Twitter that she “cracked” her head open “then kept passing out.” She said she was given the “all clear” and was released from Mercy Hospital, which declined comment Monday.

Osbourne was attending a model casting call for Madonna’s Material Girl clothing line while in Miami. Her publicist has not yet released the cause of the injury.

Pictures on her Twitter page show she was at a club Saturday night.

Osbourne found fame after appearing on the reality series “The Osbournes” alongside her family, including rock star Ozzy Osbourne. She has recorded several albums and appeared on “Dancing with the Stars” in 2009.
